To evaluate the effect of aromatherapy through inhalation of Lavandula angustifolia essential oil in relieving pain during the immediate postoperative period of patients undergoing cardiac surgery.
A single-blind, randomized and controlled clinical trial, with 52 patients in the immediate postoperative period of cardiac surgery were randomly distributed into experimental (n = 26) and control (n = 26) groups. The primary outcome was whether or not pain was relieved and secondary outcomes included changes in vital signs, sleep and facial relaxation. The control group received industry standard care and application of an essential oil-free ceramic diffuser necklace. The experimental group received the inhalation intervention with pure Lavandula angustifolia essential oil, with a drop of the oil on a ceramic diffuser necklace at a distance of 15-20 cm from the patient's nose for 30 min. Pain was measured using the Numerical Visual Scale, and vital signs using the multiparametric monitor before the intervention, 10 minutes after its start and 30 minutes after the total end of inhalation. Face relaxation was assessed before and after the intervention and sleep was assessed at the end of inhalation.
There was a decrease in pain levels (p < 0.001) 30 min after the end of inhalation in the Experimental Group, with a decrease in the measurements of Mean Blood Pressure (p= 0.008) and Respiratory Rate (p = 0.011). Furthermore, facial relaxation and sleep had a large effect size of 2.54 and 1.28, respectively.
Lavandula angustifolia essential oil was effective in relieving pain, causing sleep and relaxation, proving to be a low-cost and easy-to-use tool that the nursing team can use in their care.
评估通过吸入薰衣草精油缓解心脏手术后患者即刻术后疼痛的效果。
这是一项单盲、随机对照临床试验，共有 52 名心脏手术后即刻期的患者被随机分为实验组（n=26）和对照组（n=26）。主要结局是疼痛是否缓解，次要结局包括生命体征、睡眠和面部放松的变化。对照组接受行业标准护理和无精油陶瓷扩散项链的应用。实验组接受纯薰衣草精油的吸入干预，在距离患者鼻子 15-20 厘米的陶瓷扩散项链上滴一滴油，持续 30 分钟。疼痛采用数字视觉量表进行测量，生命体征采用多参数监测仪在干预前、干预开始后 10 分钟和吸入结束后 30 分钟进行测量。在干预前后评估面部放松，在吸入结束时评估睡眠。
实验组在吸入结束后 30 分钟疼痛水平下降（p<0.001），平均血压（p=0.008）和呼吸频率（p=0.011）的测量值也下降。此外，面部放松和睡眠的效应量分别为 2.54 和 1.28。
薰衣草精油能有效缓解疼痛，促进睡眠和放松，是护理团队在护理中可以使用的一种低成本、易于使用的工具。
